Even if it did taste 20 times better - even if it tasted 40 times better - you can get such good wine for $10 that I'd rather have twenty $10 bottles than one $200 bottle.

Well...maybe ten $20 bottles anyway.

I think the biggest improvment in quality comes in that price range: $10 to $20.

Once I get past $20 a bottle I usually can't tell the difference compared to the higher priced wines, where I can with a $10 wine vs. a $20 wine.
